Description

[Detailed description of the invention] Industrial applications The present invention relates to a handling depth control method for a combine harvester.

BACKGROUND ART Conventionally, the shell culm that is harvested by the front reaping device is transferred and supplied from the shell culm supply device to the rear threshing device by the running of the traveling device for threshing processing. To adjust the feeding depth of the shell culm supplied to the shell culm, each depth sensor is provided to adjust the movement of the shell culm supply device, and each depth sensor detects the supply shell culm as the shell culm supply device moves. It was a handling depth control method.

Problems to be Solved by the Invention While the traveling device is running, the husk culm is harvested by the reaping device, and the cut husk culm is clamped and transferred by the husk supply device to be supplied to the threshing device, and this supplied husk culm is transferred to the threshing device. Threshing is done in
The movement of the culm feeding device is adjusted according to the length of the culm to be harvested, and by adjusting the movement of the culm feeding device, each treatment depth sensor detects the tip position of the supplied culm and controls the handling depth. In this method, a motor for adjusting the movement of the culm feeding device,
If a malfunction occurs in each of the threshing depth sensors, it may not be possible to control the threshing depth, or it may only be possible to control shallow or deep handling. In some cases, additional power may be required, and unhandled material may be left in the supply culm.

Means for Solving the Problems This invention provides a means for moving the husk to be harvested by the front reaping device (2) by the running of the traveling device (1) from the husk supply device (3) to the rear threshing device (4). In a combine that transfers and feeds grains for threshing processing, the culm supply device (3) to the threshing equipment M (4)
Depth sensors (5) and (6) are provided to detect the feeding depth of the shell culm supplied to the shell and move the shell culm supply device (3) to a predetermined depth. A combine harvester characterized in that handling depth control is determined based on the presence or absence of a detected change in the handling depth sensors (5), (6) after a predetermined time period has elapsed since the feeding depth adjustment by moving the shell culm feeding device (3). The structure is based on a handling depth control method.

Effect of the Invention While the traveling device (1) is running, the husk culm is harvested by the reaping device (2), and the cut husk culm is clamped and transferred by the husk culm supply device (3) and supplied to the threshing device (4). This supplied shell culm is threshed by this threshing device (4), and depending on the length of the shell culm to be harvested during this reaping operation, the shell culm feeding device (3)
By adjusting the movement of the shell culm supply device (3), the position of the tip of the supplied shell culm can be determined by the various depth sensors (5), (
6), and based on this detection, the handling depth of the supply shell culm is controlled. In order to change the handling depth of the supply shell culm, the shell culm feeding device (3) is moved and adjusted and a predetermined period of time elapses. When the respective class depth sensors (5) and (6) detect a change in the feeding depth of the feeding shell culm as the shell culm feeding device (3) is adjusted to move, the processing depth is accurately controlled. Contrary to the above, even if a predetermined period of time has elapsed, each handling depth sensor (5),
If (6) does not detect a change in the feeding depth of the feeding shell culm, it is determined that the handling depth control is not being performed accurately.

Effects of the Invention According to this invention, the threshing equipment ffl is removed from the grain culm feeding device (3).
(4) In order to change the supply depth of the supply shell culm, the shell culm feeding device (3) is moved and adjusted, and after a predetermined period of time has elapsed, the supply depth of the supply shell culm is detected at each handling depth. Sensor (5
), (6) detects a change in the feeding depth of the feeding shell culm,
By determining that the handling depth control has been performed accurately, the threshing device t(4) will not require more power than necessary, and the culm to be supplied will not be left unhandled.
